PICTURE AP- TYPE assignor, by memo Company, Jer- New Jersey In Great Britain February 5, 1836 3Claims.

The present invention relates to a guide member for motion picture apparatus of the magazine type and more particularly to a guide member which compels tilting of the film magazine during insertion into or removal from the magazine chamber of said apparatus. Such a guide member is disclosedbut not claimed in my copending application, Serial No. 1372, filed January 11, 1935, for mprovements in an Ejector for motion picture apparatus of the magazinetype.

The primary object of the present invention is the provision of a guide member which extends lnto the magazine chamber of a motion picture apparatus and which lies over a portion of the film magazine to compel tilting of the magazine during insertion or removal thereof.

Another object of the invention is the provision of a guide member which has a resilient portion for engaging a surface of the film magazine for holding the magazine in position and at the same time for compelling tilting of the magazine for its insertion or removal. Other and further obiect's of the invention will be suggested to those skilled in the art by the disclosure which follows.

The above and other objects of the invention are obtained by merely providing a guide or spring member which extends into an open sided magazine chamber of a motion picture apparatus,

said guide or spring member overlying or over- I so lapping the film magazine to compel tilting thereof during removal or insertion and including the resilient portion for positioning the magazine after insertion.

Reference is hereby made to the accompanying edrawing wherein similar reference characters designate similar elements and wherein:

Fig. 1 is a side elevation of a motion picture apparatus of the magazine type which is equipped with a guide member according to the invention.

10 Fig. 2 is a fragmentary view of the apparatus film advancing mechanism and a cross section of the magazine wall.

Fig. 3 is a fragmentary section of the magazine wall showing the closure means for the mag- ,5 azine in closed position.

Fig. 4 is a longitudinal section through the apparatus showing the film magazine in tilted position.

The invention is to be described with respect 0 to a motion picture camera but it is to be understood that the invention may also be used in connection with other kinds 'of motion picture apparatus of the magazine type, such as projectors, J- printers, etc.

5 The motion picture camera comprises a cashas be operated ing I 0 and ing II! which contains a cover plate it which carries a latching bar It which can by a button [5 on the exterior of caewhich carries a saddle piece 58 for perating the closure means on the film magezine.

The magazine chamber is formed within said casing I Fig. 4,

0 and is enclosed by a side wall ll, by edge Walls l8 and I9, by an edge wall H, see

and by the support member 20. The film magazine 21 is located within said magazine chamber by a spring 22 which bears on the rear magazine 2! to press the front of the magazine against the rear surface of front edge wall I I,

while a second spring 23 bears upon the upper edge of film magazine 2E and presses the lower ed ber 20.

ge of the magazine against support mem- A film advancing mechanism is located within casing l 0 and includes a driving eccentric 24, a

claw arm 25 pivotally connected to said driving 26 into the magazine chamber.

The film magazine, see Fig. 2, comprises 2 casing with a side wall 29 and an edge wall 29 extending around the edge of wall 28. An auxiliary upper portions thereof, being A is slidable between edge wall 29 and auxiliary wall 39, being operated by a pin 32 which extends portion through a slot 33 in the upper of edge wall 29 and which fits into the saddle piece [6 on the latching bar M. The front portions each provided claw openings may be to closed position. The film F is held across the inner aperture 35 by a i n.

of edge wall 29 and auxiliary wall 9e are with exposure apertures 34 and 35, which apertures and openings covered by shutter 3| when it is moved in position 34 and inner opening presser member 26 of conventional de- 3, said claw 26 still of the magazine edge wall 29. As a overlies or overhangs the edge result it is not practical to remove the film magazine by'direct lateral movement from the magazine chamber but removal the film magazine 2i should be tilted for or insertion in the manner illustratedin to edge wall 28 and extends mechanism indicated.

A guide member 31 extends into the magazine chamber and overlaps a portion of the film magazine 2i. Said guide member 31 may include a spring portion 38 for resiliently engaging a porvstion of film magazine 2| to hold the side wall 28 of the magazine against the side wall I! of the camera. Specifically member 37 may be set into a recess 39 provided in raised portion i2 of cover plate i I by means of a bolt 60.

The initial movement of film magazine 2i for removal from the magazine chamber may be accomplished by an ejector mechanism including a brace M and a pin 62 both of which are fully disclosed in my aforementioned copending application, Serial No. 1,372, filed January 11, 1935. The

provision of such ejector mechanism, optional.

however, is

The film magazine 2! must have its forward edge inserted under the guide member 37 during insertion of the magazine and as a result the claw 2B of the filmadvancing mechanism will enter the claw opening 35 as the remainder of the film magazine is swung into proper position. Conversely, in order to remove the magazine the rear edge or portion of magazine 2! must be raised, either manually or automatically by the ejector Complete removal of film magazine it can only be'accomplished by further tilting of the magazine and then withdrawing the same from the magazine chamber. Consequently, the film magazine 2 i must be tilted either for insertion into or removal from the magazine chamber. I

It should also be noted that the guide member 3? not only functions to :compel the aforementioned tilting of themagazine but also aids" in properly locating camera by virtue of its resilient pressure against the forward portion of film magazine 26 over the edge wall 29 which is provided with the claw opening 35. My invention herein described is susceptible of many variations and the present disclosure is to be construed in an illustrative sense, the scope of the invention being defined by the claims which follow.

Having now particularly'described' my invention, what I desire to secure by Letters Patent of the United States and what I claim is:

said film magazine can the film magazine within the 1. Ina motion picture apparatus of the magazine type, the combination with a casing including a side wall and edge walls, which walls form a magazine chamber with an open side, and a'film magazine having such dimensions as to substantially fill said magazine and such that said film magazine can be inserted into said chamber only through the open side thereof, of a guide member on said casing, extending into said magazine chamber, and having a portion for engaging and guiding said magazine during its insertion into said magazine chamber and for engaging and definitely positioning said magazine after such insertion into said chamber.

2. In a motion picture apparatus of the magazine type, the combination with a casing including a side wall and edge wal1s,which walls form a magazine chamber with an open side, and a film magazine having such dimensions as to substantially fill said magazine chamber and such that v be inserted into said chamber only through the open side thereof, of a spring member on said casing for overlying and engaging a portion of said film magazine resiliently to maintain said magazine against the side wall of said chamber and for pelling tilting of said magazine during insertion into or removal from said magazine chamber.
